empty a bag of them across the floor as a make shift alarm system so if any one tries to sneak in your house you can hear the chips crunching under their feet...or the crunching to them picking them up and eating them as they get closer :p

I predict that each time you do this, the number of friends you have will momentarily increase, and they will wish to hang out.

I'll take a potato chip and...stare at it. Then I would...stare at it some more....lastly, I'd lose the staring contest between me and the potato chip, throw it to the ground, and smash it into little tiny pieces and laugh maniacally at the potato chip as it suffers the fate of being horribly crushed!!!

Find someone bigger than you, subdue them. Then put a saddle on their back. Once that is done you take a potato chip, tie a string around it and then tie the other end to a stick. Now mount your trusty new steed and proceed around the neighborhood in gloating as they desperately attempt to eat that chip that's dangling in front of their face.
